Background
The railway track is very frequently used due to the particularity of the railway track, the force applied to the railway track is very complex, the displacement and abrasion of the track are easily caused, the track displacement can cause the change of the track gauge, the most common track abrasion is corrugation, and huge potential safety hazards are brought to the running of a train, so that the regular detection of the track gauge and the corrugation is very necessary, and the efficient, quick and accurate detection device of the section parameters of the steel rail is very important due to the long and complex railway line in China.
The measuring method of the track gauge is generally divided into a contact type measuring method and a non-contact type measuring method. The contact type measuring method is characterized in that the detection of the track gauge is realized by adopting an eddy current type sensor, the measuring method is low in detection speed and measurement precision, detection equipment is easy to damage, the contact type track gauge measuring method does not adapt to requirements any more along with the improvement of the running speed, the track gauge detecting method widely adopted at present is a non-contact type measuring method, the principle and the structure of the non-contact type track gauge measuring method adopted by various countries are different, and the defects of poor stability, large environmental influence, high price and the like generally exist.
The traditional rail corrugation measuring method mainly comprises an artificial caliper method, an inertia reference method, a chord measuring method and a machine vision method, wherein the artificial caliper method is used as a corrugation curve of the section position through the fluctuation change of a vernier caliper which is in contact with the surface of a rail along a straight rule walking belt of 1m, the efficiency of the method is too low, the position of a contact zero point of the straight rule and the surface of the rail is influenced by the deformation and the surface damage of the rail and is not usually on the same horizontal plane, and therefore the measuring precision is influenced. The method can accurately describe the rail corrugation with the wavelength of 100 mm-50 m, but the measurement accuracy is greatly influenced by the running speed and the irregularity of the wheel tread. The chord measuring method utilizes the inherent transfer function relationship between chord measuring value and corrugation value constructed by a plurality of displacement sensors, and carries out secondary processing on the chord measuring value by designing a corresponding inverse filter, so that the output waveform approaches the real appearance of track corrugation, compared with an inertial reference method, the measured value is not influenced by the running speed of a vehicle body, but because the random vibration of multiple degrees of freedom possibly occurs in the advancing process of the vehicle body, the measurement point is difficult to be ensured to be always positioned in the effective range of a rail top, a machine vision method extracts Gabor texture characteristics from the whole steel rail image, then a K-neighbor method is applied to carry out corrugation identification, and a higher identification effect is obtained, but the method is based on the global characteristics of the steel rail image, the Gabor filtering speed is slower, an offline model training process is also needed, the use is inconvenient, the existing detection device only can detect the rail distance or the steel rail corrugation, cannot be integrated and has single function.
